PUNCHING AND CUTTING LPLIERS.

' Specification of Letters Patent.

Patented June 7, 1921.

Application filed August 5, 1920. Serial No. 401,404.

of iowa, have invented a new anduseful Punching and Cutting Pliers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to punching and cutting tools and has for: its object to provide a tool of this character of the pivoted cross member type, one of said jaws of which is provided with a cylindrical bore for the reception of the end of a sewing machine strap. The other j aw is provided with an adjustable knife which will shear off the end of the belt at the same time that a punch is forced through the belt forforming an aperture adjacent the end of the bel said belt passing through the cylindrical belt receiving member of the lower jaw.

A further object is to provide a right angled shaped knife member having one of its flanges provided with an elongated slot adapted to receive set screw which passes through said slot and into one of its the angled knife member may be adjusted in relation to the belt punch.

ll ith the above and other objects in view the invention resides in the combination and arrangement of' parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes in the precise embodimen' 'cof the invention may be made within the scope of what is cl imed without departing from the spirit 1e invention.

1 the drawings 5; igure 1 is a side elevation of the cutting i punching tool.

2 1s a front elevation the tool.

. 3 is aside el vation of the jaw end tool showing the jaws in section.

'. a: is a detail perspective view of a erring to the drawings, the numeral 1 des gnates the punching and cutting tool ich comprises cross handles 2 and 3 which are pivotally united as at 4. Handle member terminates in a a, while the handle j aws, said set screw forming means whereby memberQterminates in ajaw 5. Jaws 4 and 5 are recessed as at 6 so as to form a rectangular shaped recess 7. The forward end of the jaw 5 is provided with a longitudinally disposed aperture 8, in which aperture the end of the belt 9 which is to be cut and punched is placed while the jaws are in open position. The longitudinally disposed aperture is preferably of substantially the same diameter as the belting 9 so that said belting will be securely held during a cutting and punching operation. The ragged end of the belting is severed by the knife flange 10 of an adjustable plate 11, said'plate be ing at right angles to the knife 10 and provided with an elongated slot12, to which slot the-set screw 13 extends and is threaded into the upper jaw 4. By adjusting the knife 10 in relation to the inner end of the aperture 8, it will be seen that the distance of the hole 14 from the severed end may be gaged. The hole 14 is placed in the end of the belt by a punching member 15, which punching member is threaded in an aperture 16 of the jaw and is adapted to pass clownwardly through the apertures 17 in the aw 5, said apertures 17 being diametrically disposed in relation to the longitudinally disposed aperture 8.

In sewing machine belts, it has been found extremely difficult to place the coupling 18 in position on the adjacent end of the belt 9, and the proper positioning of the holes 1% in relation to the ends of the belt, however, by providing a tool h may sever the ragged end of the belt at a rightangle to its axis and simultaneously pierce the belt at a point the proper distance from the severed end, these diiiiculties are overcome. knife it will adjusted for different sizes of couplings and belts. will also be seen that a tool is provided which is compact, sirriple of construction and one wherein th partsare reduced to a minimum.

The invention having been set forth what is claimed as new and useful is A belt cutting and punching tool comprising cross members, said members beir oted together and provided at one o; ends with hand engaging members and'their other ends with aws, one if H a longitu By providing an adjustable so I be seen that the knife may be end of the leugiituiiiually disposed i1 perture, and Wl'iii.0fiii.' f "(iii-mused apertures in one of said jaws and dimuwtiii-uliy disposed in relation in the riiiuh'ii-M apertures, :2 (1eiizu'hnhie iuim'hihpj li illlkllii (111311.011 by the other jn'w and 11m imsitimiud that ii: will pass thim 1 the iiiz'mieti'ivz'iiy disposed aper- "tm' i i'he :ui uu-eut 1313* when said JZLWS Z\ ui'e 'it'i, 11 iifjil'il i'tli il'id si'iuped knife piste iiispeswi in, the invests M? the upper jziu mu:- ul the i'iung es of snii li right mu led knife pinto heiug proi'ii led with means for seem-iii; and iuijusi'ilig the same in the recess of the upper jaw and a knife edge carried by the lower end of the other 15 right angled flange and adapted to shear 0h :the end of the belt simultaneously with the punching and pierviug operation.

In testimony whereof I have signed my name to this spevifit-ution in the presence of 20 two suhsvrihing witnesses.
